The fire stones carry: Ethnographic records and archaeological expectations for hot-rock cookery in western North America

Ethnographic data from Kalispel elders in the 1930s attest to use of wild root foods, rock-filled earth ovens, steaming and boiling pits, and hot-rock griddles during the 1800s in forested montane regions of the interior Northwest. Cabeza de Vaca’s narrative of his 1528–1536 travels across the Gulf Coastal Plain of Texas and deserts of northern Mexico illustrates the importance of root foods, earth ovens, and stone boiling in aboriginal Southwest North America. These and other accounts, results of actualistic experiments, and knowledge of cooking requirements afford reliable bases for generating archaeological expectations about fire-cracked-rock assemblages representative of diverse cook-stone facilities.     

Determining the Provenance of native copper artifacts from Northeastern North America: evidence from instrumental neutron activation analysis

The emergence of archaeological interest in native copper in the mid-1800s developed in concert with explanations that privileged the Lake Superior area over other potential sources of copper. Most scholars have thus assumed that when copper artifacts first appeared in Northeastern North America, they arrived as finished implements or were locally made from Lake Superior raw materials. Procurement models that point to Lake Superior as the sole source of native copper have been widely accepted in the absence of systematic large-scale testing. This article evaluates the dominant model for native copper procurement and presents trace element data derived from instrumental neutron activation analysis (INAA) to determine whether hunter-gatherers in the Northeast utilized one dominant source of copper or in fact exploited a number of geological deposits. I specifically report on the chemical characterization of copper from 13 discrete geological deposits and 18 archaeological sites dating to the Late Archaic (ca. 5000–3000 B.P.) and Early Woodland (ca. 3000–2000 B.P.) periods to suggest that the dominant model for native copper procurement is oversimplified.     

Flake scar patterns of Clovis points analyzed with a new digital morphometrics approach: evidence for direct transmission of technological knowledge across early North America

Clovis points are the principal diagnostic artifacts of a Clovis complex that spread across North America between ca. 11,050–10,800 radiocarbon years before present. Clovis may be the best documented Paleoamerican culture in North America, but much remains to be learned about the movement and interactions of Clovis peoples. Similarities among Clovis points from geographically diverse locations have led some researchers to suggest that a uniform projectile point technology existed across North America during Clovis times. Others have rejected this idea, proposing local and independent technological adaptations to different regional environments. To investigate these ideas, we used digital morphometrics to analyze 50 Clovis points from nine different contexts. First, 3D surface models of the points were created with a portable laser scanner. Next, these models were digitally cross-sectioned through both faces, yielding two-dimensional isoheight contours of flake scar patterns that reflect the original reduction techniques used to shape the projectile points. In the final step, the contours were transformed with elliptic Fourier analysis into Fourier coefficient series, and patterns of variation and symmetry were explored with principal components analysis. When compared to modern Clovis point replicas made by an expert knapper, the flake scar contours of the ancient Clovis points showed little morphological variation and a large degree of bifacial symmetry. Our results support the existence of a widespread standardized “Clovis” knapping technique, most likely transmitted through direct interaction between knappers from different groups.     

The Organization of Later Stone Age Lithic Technology in the Caledon Valley, Southern Africa

Paleoclimatic data indicate that the Pleistocene/Holocene transition was a period of considerable ecological change in the Caledon Valley of the southern African interior. Stone artefact assemblages from sites in one part of this region, the Phutiatsana ea Thaba Bosiu (PTB) Basin of western Lesotho, were analyzed in order to investigate whether changes in settlement and subsistence strategies during this period are also reflected in the organization of lithic technologies. It appears that although technological solutions to the problems of subsistence risk may have been emphasized during the late Pleistocene, social means, such as exchange, dominated at the Pleistocene/Holocene boundary. Subsequent innovation or adoption of new formal tool types suggests that both strategies were important from the middle Holocene onwards.Dans la vallée de Caledon à l'intérieur sud-africain les données paléoclimatiques indiquent que la transition du pléistocène à l'holocène était une période de changement écologique considérable. Les résultats des analyses des outils lithiques découverts aux gisements dans une partie de cette région, le Bassin de la Phuthiatsana ea Thaba Bosiu (PTB) du Lesotho occidentale, sont présentées pour examiner si des changements aux stratégies de subsistance et de l'occupation des sites se réfletent à l'organisation des technologies lithiques. Il semble que on a employé les solutions technologiques pour éviter les risques de subsistance pendant le pléistocène tardif, mais que des solutions sociales, comme l'échange, prédominaient à la frontière pléistocène-holocène. L'innovation ou l'adoption plus tard des nouvelles outils lithiques suggère que tous les deux stratégies étaient importantes depuis le début du moyen Holocène.     

Long-term developments in complex hunter-gatherer societies: Recent perspectives from the pacific coast of North America

The Pacific coast of North America is ideally suited to the study of long-term developments in complex hunter-gatherer societies. This paper synthesizes current research in California and the Northwest Coast on three related research problems. The first concerns the timing, spatial distribution, and economies of the earliest coastal peoples in the region. The second problem involves the growth and florescence of complex Pacific hunter-gatherer societies. What constitutes archaeological evidence of hunter-gatherer complexity, when and where it occurs, and the interpretations proposed to account for it are reviewed. The final problem addresses how complex hunter-gatherer peoples responded to European exploration and colonization, and how these early encounters affected the Pacific coast societies recorded in early ethnohistoric accounts and later studied by ethnographers.     

Interpreting pachyderm single carcass sites in the African Lower and Early Middle Pleistocene record: A multidisciplinary approach to the site of Nadung’a 4 (Kenya)

Nadung’a 4 is one of the single carcass pachyderm sites recorded in East Africa during the Lower and Early Middle Pleistocene. The site has yielded an abundant lithic assemblage in close association with the partial carcass of an elephant. Conjoined pedological, geoarchaeological, spatial, technological, and taphonomical analyses have been carried out to address the relationship between hominids and elephant. The resulting data are consistent with a non-fortuitous association between both categories of remains. The lithic artefacts do not match a classical Acheulean tool-kit, as would be expected for the time period ascribed to the site, and the functional patterns inferred from their analysis make this site radically different from other purported butchery sites. The implications of these original features are discussed.     

Standing at the gates of Europe: Human behavior and biogeography in the Southern Carpathians during the Late Pleistocene

This study presents a behavioral analysis of Middle and Upper Paleolithic lithic assemblages from 14 sites located in the southern Carpathian Mountains. Using a whole assemblage behavioral indicator, we show that the hominins that manufactured those stone tools do not appear to have differed in terms of the flexibility of the mobility strategies they employed to exploit their landscapes. Rather than biological change, we argue that large-scale climate changes are likely more important drivers of behavioral changes during the Late Pleistocene of the region, including during the Middle–Upper Paleolithic transition. These results agree well with the results of studies having employed this methodology in other regions, suggesting that this is a generalized feature of the transition across Eurasia. Recasting the transition as a mainly ecological rather than purely biocultural process allows us to generate new perspectives from which to approach the question of behavioral change during the Late Pleistocene, and ultimately suggests that the process referred to as the ‘Middle–Upper Paleolithic transition’ is essentially a brief segment of a much more extensive process driven by prehistoric human–environment interactions that would culminate in the highly logistical mobility strategies documented throughout the continent at the Last Glacial Maximum.
